基于区域增长的轮廓线提取算法

Contour Line Extraction Algorithm Based on Region Growing

在网格序列法的基础上提出了一种改进的轮廓线提取算法———基于区域增长的轮廓线提取算法,该算法采用区域增长的方法来加速搜索边界单元,从而避免了搜索所有的网格单元。实验结果表明,本算法明显提高了网格序列法的效率,且得到的轮廓线更有利于三维形体的重建。

An improved contour line extraction algorithm based on grid sequence is presented in this paper. It is named as the contour line extraction algorithm based on region growing. The region growing searching method is used to speed up boundary grids searching speed whereby avoiding searching all of the grids. The experiment results show that this algorithm obviously improve the efficiency of the grid sequence and that the contour line obtained is more favourable to the 3D reconstruction.
